Lay out believable large engineered environments in Three.js, as systems rather than props. Use for streets, railways, stations, buildings, bridges, utilities, industrial districts, ships and any place where infrastructure has to read as working.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Engineered Environments Target: Three.js 0.187.0, WebGPU renderer (`three/webgpu`) and TSL node materials (`three/tsl`); no WebGL fallback, no GLSL. Create a coherent engineered place, not a collection of disconnected props. ## Core idea Everything exists because people live, travel, work, maintain and repair the place. Think in systems: - transport - pedestrian circulation - utilities - power - water - waste - ventilation - communications - emergency access - maintenance - structural support - habitation - commerce - industry ## Ground and orientation The ground is the local reference for everything built on it. When creating long structures, decide whether each should follow: - the ground's own surface (a road, a wall, a pipe along a floor) - a straight local tangent (a beam, a bridge span, a rail that must stay flat) - a structural direction (a column, a mast, a hanger) - an independent suspended structure (a cable, a gantry, a roof) …

How to install
mdr add wolffe/three.js-skills/engineered-environments@sha256:d7af62754ced11f3The line at the top of this page pins the label git:20261031.50d32a4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
